COMMON NOTES
2. ADU INSTALLATION POSITION
2.1. GW3060
The ADU pump must be mounted on the back, in the empty space in the vicinity of the P2 pump. Upper
position for P1, lower for P3 and P4.
The metal back of the machine is divided into two sections, watching from behind: left and right. The two
sections can be easily separated (they are fixed by cross screws and inserted at 1/4 turn and can be opened
with a flat blade screwdriver).
The right section is the one that houses the peristaltic pumps. To install the ADU pump it is necessary to
remove the pre-cut shapes on the frame. On the back of the shapes are the terminals for the electrical
connection of the pumps.
fig. 1 – 3060 back, pumps position from top to bottom, respectively: P1, P2, P3.

2.2. GW4090
The ADU pump must be installed on the peristaltic pumps casing, inside the detergents cabinet, to the right
of the machine, in the free compartment under the P1 and P2 pumps. Left position for P3, right for P4. To
install the ADU pump it is necessary to remove the pre-cut shapes on the frame. On the back of the shapes
are the terminals for the electrical connection of the pumps.
fig. 2 – GW4090, the peristaltic pumps for detergents are housed in the right cabinet.
2.3. GW2045
The ADU pump must be assembled to the rear low panel (or “crossbeam”).
To install the ADU pump it is necessary to remove the pre-cut shapes on the rear crossbeam.
Remove the pre-cut shape, which covers the pre-assembled electric wiring. Cut the plastic tie and use the
wiring to connect the pump.
fig. 3 – GW2045, pumps are located on the rear crossbeam. Rear view: P1 is on the left.

associated with the ADU pump.
3.1.1. GW3060 Old Series
The nozzle is threaded M8 and must be installed in place of one of the stainless steel caps on the
detergents inlet tap. Use liquid Teflon on the thread to improve the tightness of the component.
fig. 4 – GW3060, removing the back you have access to the point in which the stainless steel nozzle for detergent inlet must be installed..
3.1.2. GW3060 New Series
The detergent entrance into the chamber is made by a heat resistant plastic connector located on the rear
of the chamber. The application of the new pump requires the drilling of the nozzle to be used, with a drill
bit Ø 3, 5mm.
